Quantum Threats
Are Coming.
Defend the App Layer.

Post-quantum cryptography is being standardized at the protocol layer. But your application's cryptographic surface — WebCrypto calls, WASM libraries, key management patterns — remains exposed. QubitBlocker monitors, audits, and scores your domain's quantum readiness in real time.

Quantum Attacks That Reach Your Application

These aren't theoretical. Adversaries are already collecting encrypted traffic. The application layer is the blind spot.

01

Harvest-Now, Decrypt-Later

Adversaries capture your TLS-encrypted traffic today. When quantum computers mature, they factor your RSA or ECC keys and decrypt everything — session tokens, user data, API keys.

Critical — Active Now
02

Application Crypto Surface Exposure

Your JavaScript calls WebCrypto with RSA-OAEP. Your WASM module uses secp256k1. Your key derivation uses PBKDF2 with insufficient iterations. All quantum-vulnerable, all client-side.

Critical — Active Now
03

Quantum-Accelerated Probing

As quantum capabilities emerge, adversaries test them against live targets. The behavioral signature differs from classical attacks — distinct timing, unusual failure modes.

High — Emerging
04

Certificate and Key Rotation Gaps

Long-lived certificates and static API keys amplify harvest-now risk. If your TLS private key hasn't rotated in 6 months, every session it protected is potentially compromised.

High — Active Now
05

Third-Party Crypto Dependencies

CDN scripts, analytics embeds, and SSO widgets all establish their own crypto contexts. A single third-party script using SHA-1 creates a quantum-vulnerable entry point.

Emerging — Underserved
06

Post-Quantum Migration Deadlines

NIST published final PQC standards (FIPS 203, 204, 205) in August 2024. If your application can't consume PQC ciphersuites when the server offers them, you're exposed.

Emerging — Time-Sensitive

What QubitBlocker Monitors

Five detection layers operating continuously at the application boundary. No server changes required.

TLS PQC Readiness Audit

Inspects the active TLS connection's cipher suite and key exchange method. Reports whether PQC hybrid modes are active.

Crypto API Surface Mapping

Intercepts WebCrypto and SubtleCrypto calls at runtime. Enumerates every algorithm, key size, and hash function. Flags quantum-vulnerable primitives.

WASM Crypto Module Scanning

Detects WebAssembly modules that implement cryptographic operations outside the browser's native APIs by monitoring compilation calls.

Harvest-Now Risk Scoring

Combines TLS parameters, certificate age, key rotation frequency, crypto surface exposure into a 0–100 risk score.

Anomalous Timing Detection

Monitors cryptographic operation timing for patterns consistent with quantum-accelerated probing.

Third-Party Crypto Audit

Maps every script origin and checks each one's TLS parameters. Flags third-party resources that downgrade quantum security posture.

Quantum Threat Monitor

Live visualization of the detection pipeline. Toggle monitoring to observe how quantum-vulnerable crypto operations are flagged.

Deploy in One Line

QubitBlocker initializes synchronously before any application code runs. It intercepts WebCrypto, audits TLS, and begins monitoring — zero configuration required.

The Quantum Threat Timeline

The threat isn't hypothetical. The timeline is already in motion.

1994

Shor's Algorithm Published

Peter Shor proves that a quantum computer can factor integers in polynomial time, theoretically breaking RSA and ECC.

2016

NIST PQC Standardization Begins

NIST launches a formal process to evaluate and standardize post-quantum cryptographic algorithms. 82 initial submissions.

2019

Harvest-Now Attacks Confirmed

NSA and GCHQ publicly warn that nation-state adversaries are actively recording encrypted traffic for future quantum decryption.

2024

NIST Publishes Final PQC Standards

FIPS 203 (ML-KEM), FIPS 204 (ML-DSA), FIPS 205 (SLH-DSA) published. Federal agencies receive migration mandates.

2025 — Now

Application Layer Gap Widens

Servers begin supporting PQC ciphersuites, but client-side applications remain unprotected. QubitBlocker addresses this gap.

2028–2030 (Estimated)

Quantum Computers Reach Cryptographic Scale

Major programs projected to reach 4,000+ logical qubits — the threshold for breaking RSA-2048. Harvested traffic becomes decryptable.
